first of the train of gears b2, b3, b4, and b5. The last named gear is secured to the shaft through roller B. These gear wheels are mounted in pivoted arms h6 bT 118. Thus it will be seen that either of the rolls may yield against the springs G if any hard substance comes between it and one of the knives C, and yet the transmitting-gear will always be in an operative position. rlhe shaft U is driven by a belt u, running from a pulley on a shaft of one of the rollers B to the pulley on the shaft U. The levers W are formed of a main part w, to which are attached on each side bolts w, to which is fastened a strap wz, which passes over the pivot-pin in the arm I. A transverse bolt w passes through this strap and holds it to the part u.

The operation of my device is as follows: Motion is imparted to shaft X from any convenient source of power. The lever-arms W cause the arms P to rock, which imparts a reciprocating motion to the blades O. By means of the belt I one of the rollers B is driven, which drives, through the medium of the train of gearing b2, b3, b4, and h5, the other roller B, which by means of the belt il, drives the shaft U, operating the feeding device V. The cotton is then fed intof the machine. The feeding devices V reciprocate the cotton over the grates K, through the openings of which most of the seed escapes. The cotton gradually works down toward the curved knives C, under which it is drawn by the action of the rollers B aided by the reciprocation of the blades O. The seed falls toward the center of the machine and may be collected in any Way by means (not shown) such as troughs and conveyers. The ginned cotton is drawn around by the rollers B, and may then be delivered directly to the condensing-rollers or be disposed of in any desired manner. Brushes (not shown) or any other clearing means may be used outside of the rollers B, if desired. The hollow-ground knives will gin one-third more cotton in a given space than straight knives, as the friction against the elastic covering of the rollers will be greatly increased, which results in giving an increased pull to the fiber, enabling the rollers to perform their Work with much less pressure against the knives. This results in a further advantage in that the elastic covering of the rollers is subject to less wear.

It is obvious that many changes might be made Without departing from the spirit of my invention, and I do not confine myself to the exact details described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a cotton-gin, the combination of a roller provided with an elastic covering having zigzag grooves in its surface, a knife having a hollow-ground edge, the curvature thereof corresponding to the curvature of the roller,

means for adjusting said knife toward and from said roller, and feeding devices, substantially as described.

2. In a cotton-gin, the combination of rollers, yielding bearings supporting said rollers, means for driving one of said rollers, and means for driving the other of said rollers from the first roller, consisting of gear-Wheels attached to the shafts of said rollers, and gearwheels meshing with said first-named gearwheels and supported in a frame, the parts of which are pivoted together and pivotally supported on the shafts of said rollers, knives mounted near said rollers and means for feeding the cotton to the said rollers and knives substantially as described.

3. A double-roller gin, comprising a main frame, rollers provided with grooved elastic coverings supported in said frame, a main shaft also supported in said frame, a belt passing over a pulley on the main shaft and another pulley on the shaft of one of the rollers, yielding bearings mounted in said frame and supporting said rollers, gear-Wheels mounted on the shafts of the rollers at one end of the machine, a pivoted frame mounted on said shaft at the same end, gear-wheels mounted in said frame and meshing with the gearwheels on the shafts of the rollers, adjustable knives With hollow-ground edges, oscillating blades, arms supporting said blades, a shaft supporting said arms, rock-arms connected to said shaft, and operatinglevers for said rock arms mounted on cranked portions of the main shaft, inclined seed-grates, feeding devices resting upon said seed-grates, arms pivoted to said feeding devices, a shaft having cranked portions to which said arms are connected, and a driving-belt for said shaft passing over a pulley on said shaft and another pulley on the shaft of one of the rollers, l

substantially as described.

, 4. In a double-roller cotton-gin, the combination of rollers provided with a grooved elastic covering, one of said rollers mounted on each side of said gin, knives having hollow-ground edges and adj ustably mounted adjacent to said rollers, a cranked shaft mounted between said rollers, arms secured to and extending from both sides of said shaft,blades secured to the ends of said arms and adapted to be oscillated thereby in front of the said knives and rollers, a feeding device mounted above said oscillating arms and means for imparting motion to the rollers, oscillating arms and feeding device, substantially as described.

5. In a double-roller cotton-gin, the combination with rollers provided with an elastic covering having zigzag grooves in the surface thereof, one of said rollers mounted on each side of said gin, knives having hollow-ground edges and adj ustably mounted adjacent to said rollers, a cranked shaft mounted between said rollers and extending longitudinally of said gin, arms secured to and extending from both sides of said shaft, blades secured to the ends of said arms and adapted to be oseillated thereby in front of said knives and rollers, seed-grates mounted above said oscillating arms and sloping from the center of the gin toward the rollers on either side,va barv extending the Whole length of saidseed-grate, arms pivoted to said bar, a shaft provided
